Answer:
1/4 pi × r^2
Step-by-step explanation:
Area of sector = 1/4 area of circle
titha/360 × pi × r^2 = 1/4 × pi × r^2
titha =90
Area of sector = titha/360 × pi × r^2
= 1/4 pi × r^2
Answer:
1/4 pi × r^2
Area of sector = 1/4 area of circle
titha/360 × pi × r^2 = 1/4 × pi × r^2
titha =90
Area of sector = titha/360 × pi × r^2
= 1/4 pi × r^2
